PETER NIEWIAROWSKI, OF OMAHA, NEBRASKA,

ANGLE SCREW-DRIVER.

T0 all whom t may concern.'

Be it known that I, PETER NmwiARowsxI, a citizen of Russia-Poland,residing at Omaha, county of Douglas, and State of Nebraska, haveinvented certain new and useful Improvements in Drivers, of which thefollowing is a specification. This invention relates to improvements intool holders, and particularly to types which maybe used at an anglerelative'to struction and of this disclosure,

their central axis.

Thel principal object of this invention is to provide a tool holdingdevice carrying an operative element, which may be actuated either in aplane coincident with the axis of the handle or at an angle thereto.

This object is attained by the novel concombination of parts hereinafterdescribed, and shown inv the .accompanying drawings, forming a materialpart and in which- Figure 1 is a partial side elevational, and partialsectional view taken through a tool holder made in accordance with theinvention.

Fig. 2 isa fragmentary sectional view lshowing the parts disposed inanother-'position, and l Fig. 3 is an end view of the extension element.

head portion 10 formed with two extending' elements, respectively 11'and 12, disposed at a right angle, a chamber 14, being formed in thehead element, at the axis of the angles, the chamber having a heavyplate covering 15 extending along the side of the body, and bent at anangle to providea bottom portion 16.

Formed through the angular element 11 is a bored opening 18, in which isfitted a stem 19, having an enlargement 20, resting upon the top of thebody element 11, the stem continuing into a shank 21, rigidly engaged inla handle 22, held by a transverse pin 23, the handle being of anypreferred shape whatever.

Fixed upon the shank 19, is'a bevel gear 25, its back resting againstthe wall of the chamber 14, the teeth meshing with 4another gear 26,fixed upon a stem 27 extending outy Specification of Letters Patent.

ward through the opening 28, in the angular element 12, and terminatingin an offset shouldered projection 29, which normally extends outward toa slight distance beyond the outer end of the element 12.

Similarly, another offset extension 30 forms the terminal of the shank19, which extends through an opening in the cover plate 16, and whichobviously may be rotated by operating the handle.

Formed in the outer surface of rthe angular element 12 are a pair ofundercut openings 32, receptive of the headed pins 33, simi-lar openings34, being formed through the lower cover plate 16, the pins 33 being.set in the outer end of an ovalor barrel a cylindrical bore 29, andprovided with screw threads 37, by which is attached a' hollow cap 38,containing a chamber 39, in which is operatively engaged a pair ofspring jaws 40, the same being held by screws 41, within the chamber 42,formed in the handle element 35.

A tool shank 44, is formed with an offset shoulder at its upper end 45,engageable with the Shanks 29 or 30, and is formed with an annularrecess 46, receptive of the detent whereby the shank 44 is held shapedhandle 35, having in engagement, operating implement, as the screwdriver 48 indicated.

From the foregoing it will be seen that a convenient and effectiveimplement has been disclosed, which may tool driver, comprising thecombination with a chambered body having two portions perforated atanangle to each other and providing bearings and an aperture opposite oneof said bearings, shafts journaled in' said bearings each of them havingan be used in `the` ordinary manner as a plain screwdriver or the shankterminating in an y exposed end shapedto eng-Mgel an@ rotate :n endsabove mentioned, and means for interblt or-tool and oney ofthemextendmgback; changea-bly engagl-ng said Ameans with `the l through theaperturey and the opposed"bemm loody', in line with eitherof sai'd bitengaglo ing and having a handle on its other end, ing shaft ends..
